A: Besides the elementals, the only known sentient races on Azeroth when the titans' forces arrived to subdue the Old Gods were the trolls, the race known as "faceless ones," and the aqir. Due to the Old Gods' war against the titans, as well as the extensive terraforming that followed the war's conclusion, records of what races existed before even the Old Gods' arrival have likely been lost forever.

Intelligent discussion is beyond some people; they cannot comprehend that what the author states > in-game NPC that is only see once.

Deathknight's do it using disease, blood and the power of the unholy. Warlocks do it with dark demons by their side. Mages do it with summoned arcane powers. Druids do it using the forces of nature. Rogues do it through stealth, poison's, shadows and....from behind. Paladins do it by calling to the light for aid. Shamans do it with the help of the elements. Priests do it through the holy light.
But warriors....
Warriors just fucking do it.
